To all whom it mag concem." J p Be it known that I, GEORGE A. PERRY, a

citizen of the United States, residing at Mountainviewg in the county of Uint'ai and Fitate of VVyoming, haveinventeda new and useful- Engine, oii--whieli-the following is a specification. v I

The device forming the subject matter-of this application is a rotaryengine, and one object of the invention is to provide novel] means for maintaining :the swinging abutments in engagement with the rotor; the

utility of devices of'that type to which the invention appertains.

With the above andother objects in view, which will appear as the description proceeds, the invention resides in the combina-. tion and arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention shown, can bevmade, without departing'from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in vertical section, a device constructed in accordance with the invention, Figure 2 is a side elevation wherein partsv are broken away; Figure 3 is a section takenin a plane at right angles to cutting plane in Figurel, Figure 4' is a perspective viewillustratingone of the spacers; Figure 5 is perspectiveview showing one of the abutments; Figure 6' is a perspective view wherein one of the valves appears. 2

The engine forming the subject matter of this application comprises a stator 1 including side members in theform of rings 2. Spacers 3 are located between the side members 2 and are provided with openings 4; adapted to receive securing elements 5 where by the side rings 2 are held on the spacers 3. Each spacer 3 has concaved inner surfaces 6 and 7. Each spacer 3 is provided with a tan gential inlet .8 embodying an'inwardly extended port 9. Valves 10 slide in the inlets 8 and have rounded outer ends 12. Each spacer 3 is providedat one endwith a con caved seat 11.

V Abutments 14 are mounted to swing be-' tween the side members 2 of the stator: 1,

each abutm'ent comprising an 'endt 15 so shaped? so that it will conform' to" the con:- vexedlseat 11: of? the-spacer 33 The abutment 14 is provided with an openingu=16 adapted to receive a pivot element 17 mount:-

ed in theside members2 of tl1eLstator l1 and constituting means whereby abutment 14 is carried for swinging movement, as aforesaid. The wider end of. each abutment 141 is convexed, as at 18, to move in contact with the concaved surface? of the adjoining spacer 3. Adjacent to its free end, the abutment 14: is provided with a transverse exhaust port 19. Each abutment 14 carries, at

, its pivoted end, a convexed arm 20, adapted to bear upon the rounded end 12 of the ad joining valve 10. A glance at Figure 1 will show that, in substance, the abutments 14 are mounted intermediate their ends to swing on the stator.

The rotor is denoted by the numeral 21 and may include a hub 22, spokes 23, and a rim 24, the rimhaving projecting blades 25 provided with inclined surfaces 26, the ends 6 of the blades 25 being adapted to move along the concaved inner surfaces of the spacers 3, I

and along the inner surfaces of the swinging abutments 14. The hub 22 of the rotor 21 may be mounted on a shaft 27 supported in any suitable way, i as indicated at 28 in Figure 3 of the drawings.

The steam or other fluid entering the inlet 8 traverses the port 9 and expanding between the'blade -25'and the abutment 14, causes the rotor-to turn. As the rotor turns,

the blade 25 comes into contact with the.

abutment 14, swinging the abutment 14 outwardly, the arm 20 of the abutment cooperating withthe valve 10 to cause the valve to close the port 9 thereby cutting ofi the inflow of steam. Itis to be observed that thesteam or other fluid in the inlet 8, exerting a pressure against the valve 10, causes the valve 10 to cooperate with the arm 20 on the abutment 14, thereby swinging the wider end of the abutment inwardly into contact with the rim 24 of the rotor, the inclined surface 26 of the blade 25 serving to ease the abutment 14 down on the rim 24 of the rotor. The exhaust escapes through the ports 19 in the abutments 14 and, referring to the left hand side of Figure 1, it will be seen that the distance between the blades I 25; is such that, at times the space between adjoining blades is in communication with two of the ports 19, at' once,thereby' insuring a complete exhausting of the steam, after the steam has done its work. The rotor 21 turns in a clockwise direction, when the device is in operation.

Having thus described the invention, what I claim is: i

In a rotary engine, a stator comprising side members and spacers therebetween; a rotor journaled in the stator, the spacers having inlets disposed in a substantially tangential relation with respect to the rotor and terminating in inwardly extended ports communicating with the interior of the stator; abutments mounted intermediate their ends to swing between the spacers, the

abutments being provided near their inner ends with open exhaust ports, the rotor being supplied with blades which engage the inner portions of the abutments to swing the inner portions of the abutments outwardly; and valves mounted for right-line sliding movement in the inlets, the valves constituting means for opening and closing the ports, and being constrained by fluid pressure in the inlets to bear upon the outer ends of the abutments.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature.

GEORGE A. PERRY.
